    Pictures of the headers?

    I was wondering if anyone with the Tyga header has comparison pictures with it next to the stock header. 2015-16 or 2017-up, either will do. I just ordered the Tyga header, but I have a 2017. If it doesn't play well with the exhaust I just bought, I don't mind modifying the exhaust (because...

    Under belly exhaust on 17/18 RC?

    I would like to know if the new exhaust is (basically) just an added on extra muffler to a different (but effectively the same) 15/16 style muffler behind the engine. If not, has anyone fitted the new gen header and muffler to eliminate the side can? The sleek underbelly exhaust was one of my...

    Chinese exhaust?

    Hey guys, I know this is usually a hard point for most of us, but I typically like to experiment with these things. Sometimes, it's a waste of money, and sometimes, it works out. I've been looking at exhaust for a while, and although I do like most of them, the cost gets to me a bit...

    best exhaust system

    Hello! I have broken my head looking for the best exhaust for races (with tests in Dyno) but I have not found a conclusion. I have seen a double tyga, double yoshimura, lateral akrapovic, etc. Is there any conclusion about which one performs better? Thank you!

    SSP300 Exhaust

    Has anyone else noticed that the header on the ssp300 kit appears to go completely under the motor instead of along side like the stock system does. Any ideas on why this change over stock? Also do you guys think with a normal akra can and a custom pipe the same result would be possible?
